To aZZ whom it may concern.-

Be it known that we, FRANK H. DE GUERRE and WILLIE W. DE 'LANO, citizensof the United States, residing in the city and county of San Franciscoand State of California, have invented a new and useful Reversible Sash-Window, of which the following is a specification.

Our invention relates to improvements in windows; and it consists in theconstruction and arrangement of the casing and sash by means of acertain device for reversing the sash for the purpose of washing theoutside of V the same without going outside. -It will beconnecting-lever guide-pivot.

sections of the sash, the side stiles, and their connections; Fig. 6, aperspective View of the Fig. 7 is a perspective view to show the sashturning upon the pivot H. v

A represents the window-casing; B, the fiXed side stile; C, the movableside stile; D and E, thesash-weights; F, the upper and G the lower sash;H, the sash-pivot; J, the joint of the pivot guide-lever; I, the pivotguide-lever; L,

connecting-lever; N, the joint connecting with the movable stile; O, thejoint connecting with the fixed stile; P, the sheave for the sash and.'weight-cords; Q, the'recess to receive the movable style 6. Thegrooves R, S, T, and U are for the lever I to operate in, and Vrepresents the stop for the lever I. The stop-lock WV holds the movablestile C when the lower sash is down and the Window locked, whether theupper look is employed or not. This stoplock WV is an angle-iron, (shownclearly in Fig. 2,) which is rigidly secured to the lower end inside ofthe movable stile C. When the dasher G is fully down, it rests upon thisangleiron, and consequently the style C cannot be lifted. Thespring-lock Y also prevents the stile C from being raised, and theangle-iron is an auxiliary device thereto.

The following is the construction of our improved windows: We form thecasing A in appearance similar to the ordinary windowcasing, and placethe fixed side stile, 13, back, as shown, and form the recess to receivethe movable style 0. The movable stiles C have the guide-grooves R, S,T, and U for the lover I to operate in, and the stop V catches the leverI when the window is to be washed, as will be shown. The window israised and lowered like other windows now in use, the

guide-lever I falling into the side rail of the sash and leaving thesash to slide up and down like an ordinary sash; but when the window isto be washed or cleaned the sash is raised to the top of the frame,where the upper corner of the sash strikes the lock-spring Y, throwingthe same out. The movable side stile, C, is then raised, swinging backfrom the sash, freeing the same from the sash-grooves,

parting-bead, &,c., and allowing the sash to swing or revolve freelyupon the pivot or journal H, while the lever I is held by theweight-cord out into one of the grooves R, S, T, or U. The sash F or Gis then lowered until the lever I passes behind the stop-bar V, thusstopping the sash and holding the same firmly at the proper point to bewashed and swung around, turning upon the pivot H and' bringing theoutside of the glass so as to be washed from the inside of the window.When the glass is washed, the sash is replaced by raising the same untilthe lever I is raised out from the rest V, and the movableside' stile,C, is brought down so that the sashgrooves in the same embrace the edgesof the sash in the usual way, and at the same time the spring Y passesunder the top bar of the frame and locks the side stile in the positionshown in Fig. 2. The lever I is kept from rising higher than shown inFig. 5 by the projections or points Z Z.

We do not confine our invention to the holding of the sash for washing,for it may be employed for ventilation, or for operating screens orother slides employed for windows, such as sliding blinds.

Having thus described our invention, what we claim and desire to secureby Letters Patout, is-

1. In windows, the combination, with a window-casing grooved andprovided with a fixed stile, B, of a vertically and laterally movablestile, 0, connected by links M to said fixed stile, and Verticallygrooved, as described, of the sash provided with a pivot recessed intoit, an angular lever hinged to this pivot and attached to a sash-weightcord passed over a pulley, the extension-guide I, adapted to be receivedin a vertical groove in said movable stile, and a device for lockingdown the said movable stile, substantially as described.

2. The improved article of manufacture for the purpose described,consisting of the angular lever L, perforated and provided with acontracted extension I and stops Z Z, in comeeezae
